Multiply until my Pc freezes

The video likely worked due to its satisfying visual progression and the inherent curiosity of seeing how many balls the simulation could handle before crashing, tapping into the 'oddly satisfying' and 'viral simulation' trends.

The video shows a simple simulation where a single ball multiplies and bounces around a confined space. The number of balls increases rapidly over time, filling the screen and eventually causing the simulation to slow down, implying the "Pc freezes" as stated in the title.
